Just make this read:

       def doStuff(self, unused = None):

PyQt tries to cope with a small arkwardness of signals and slots here, 
inherited from Qt: Qt handles superfluous arguments to slots gracefully 
(by ignoring them). Due to the dynamic nature, that's not that easy to 
archive properly in python. PyQt resorts to try to call the slot with 
the number of given arguments down to none until it succeeds. 

BTW, it's way easier to use layouts, even in hand written dialogs. 

Otherwise, this forum would have been labeled VisualBasicNonQt, and I 
wouldn't attend here..
